Australia says it will support New Zealand's bid for a seat on the United Nations Security Council.

New Zealand is lobbying for a non-permanent position on the UNSC in 2015/16 under the Western European and Others Group.

It is pitted against Spain and Turkey and needs 129 votes from the 193 UN member states.

Australia's Foreign Minister Julie Bishop says Australia, which currently has a seat on the council, will support New Zealand's bid.

"You can absolutely count on our vote, and if there are any lessons that we've learnt from our experience, we'll be only too happy to pass them on," she told TVNZ's Q+A program.

Prime Minister John Key and Foreign Minister Murray McCully had done a good job at advocating New Zealand's interests to the UN recently, Ms Bishop said.

"So we hope that whatever support Australia can provide, we will do so, and we hope that New Zealand is successful."

The elections will be held next year.

Pacific leaders have also confirmed their support for New Zealand's bid.

New Zealand last held a UNSC seat in 1993 and 1994.
